It depends honestly. Both are prone to doing the exact opposite of what you asked. Especially with poor context management.
I’ve had both $200 plans and now just have Max x20 and use the $20 ChatGPT plan for an inferior Codex.
My experience (up until today) has always been that Codex acts like that one Sr Engineer that we all know. They are kind of a dick. And will disappear into a dark hole and emerge with a circle when you asked for a pentagon. Then let you know why edges are bad for you.
And yes, Anthropic is pivoting hard into everything agentic. I bet it’s not too long before Claude Code stops differentiating models. I had Opus blow 750k tokens on a single small task.
